Installation

Requirements

This machine will act as the OpenNebula server and therefore needs to have
installed the following software:

ruby >= 1.8.5

sqlite3 >= 3.5.2

xmlrpc-c >= 1.06

openssl >= 0.9

ssh

sqlite3-ruby gem

Additionally, to build OpenNebula from source you need:

Development versions of the sqlite3, xmlrpc-c and openssl
packages, if your distribution does not install them with the libraries.

scons >= 0.97

g++ >= 4

flex >= 2.5 (optional, only needed to rebuild the parsers)

bison >= 2.3 (optional, only needed to rebuild the parsers)

libxml2-dev

Ruby Libraries Requirements

A set of gem requirements are needed to make several components work. We
include a handy script to install them and the requirements. It is located at
share/install_gems/install_gems and you should use it to install the
required gems. You have more information at:

If you want to install them manually here are the list of required rubygems:

OpenNebula and clients (plus cloud interfaces)

sqlite3

json

sequel

mysql

net-ldap

amazon-ec2

rack

sinatra

thin

uuidtools

curb

nokogiri

OpenNebula zones (client and server)

json

sequel

sqlite3

mysql

nokogiri

Sunstone server

json

rack

sinatra

thin

sequel

nokogiri

Optional Packages

These packages are not needed to run or build OpenNebula. They improve the
performance of the user-land libraries and tools of OpenNebula, nor the core
system. You will probably experiment a more responsive CLI.

First install rubygems and ruby development libraries

ruby-dev

rubygems

rake

make

Then install the following packages:

ruby xmlparser, some distributions include a binary package for this
(libxml-parser-ruby1.8). If it is not available in your distribution
install expat libraries with its development files and install xmlparser
using gem:

$ sudo gem install xmlparser --no-ri --no-rdoc

Note the extra parameters to gem install. Some versions of xmlparser have
problems building the documentation and we can use it without documentation
installed.

ruby nokogiri, to install this gem you will need libxml2 and
libxslt libraries and their development versions. The we can install
nokogiri library:

$ sudo gem install nokogiri --no-ri --no-rdoc

Building

Compilation is done using scons command:

$ scons [OPTION=VALUE]

The argument expression [OPTIONAL] is used to set non-default values for:

OPTION VALUE
sqlite_db path-to-sqlite-install
sqlite no if you don't want to build sqlite support
mysql yes if you want to build mysql support
xmlrpc path-to-xmlrpc-install
parsers yes if you want to rebuild flex/bison files

Installation

OpenNebula can be installed in two modes: system-wide, or in self-contained
directory. In either case, you do not need to run OpenNebula as root. These
options can be specified when running the install script:

$ ./install.sh install_options

where install_options can be one or more of:

OPTION VALUE
-u user that will run OpenNebula, defaults to user executing
install.sh
-g group of the user that will run OpenNebula, defaults to user
executing install.sh
-k keep current configuration files, useful when upgrading
-d target installation directory. If defined, it will specified
the path for the self-contained install. If not defined, the
installation will be performed system wide
-c only install client utilities: OpenNebula cli, occi and ec2
client files
-r remove Opennebula, only useful if -d was not specified,
otherwise rm -rf $ONE_LOCATION would do the job
-h prints installer help
